STAPLE MAKING AND DRIVING MACHINE.-

Original application iilcd March 26, 1915, Serial No. 17,182. Patent No. 1,327,196, dated 1920. Divided and this application filed January 27, 1919. 'Serial No. 273,452.

' ceased, late of Boston, in the county of Suffolk and State of Massachusetts, invented certain Improvements in Staple Making and 7 Driving Machines, of which the following description, in connection with the accompanying drawings, is a specification, like refer-. ence characters on the drawings indicating like parts in the several figures.

This invention relates to machines for inserting fastenings and. particularly to machines which form staples from a continuous stri of material such for exam le as wire P a a and drive them into. stock.

The machine in-which the invention is shown as embodied is of the general t pe disclosed and claimed inUnited States tters Patent to W. H. Borden No. 1,016,930,

granted February 13, 1912. In this type of machine the feeding mechanism for the .staple stock comprises feed rolls which are arranged in vertical alinement, thus bringing the lower feed rollso near the plane of stapling operations as to interfere with the desired adjustment of the work with respect to the fastener inserting mechanism in certain special operations as, for instance, in lasting operations on stitchdown shoes wherein it is desired to drive staples along the forepart of a lasted shoe and down into the shank and alongthe heel seat portion. During these and similar operations, it is necessary to va the angular relationship, in the vertical p ane, of the work with respect to the fastening guiding nozzle.

It is an object of the present invention to provide an improved stapling machine of the general type disclosed in said- Letters Patent so organized as to admit of free manipulation of the work in the operation of' driving fastenings into various portions thereof.

In a preferred form of the invention, the feeding mechanism for the staple stock is so constructed and arranged that the feed members are located in substantially horizontal alinement with one of the members laterally movable with respect to the other. H

Other objects and important features of the invention will appear from the followv Specification 01' Letters I atent. Patented A 30; 1921 ing description and claims when considered n connection with the ace mpanying draw- 1I1%2 1I1 which; 4

'];h1s application is a division of applicat1on, Ser. No. 17,182, filed March 26, 1915, for a staple lasting machine, which has issued as Patent No. 1,327,196, granted J anuaryr 6, 1920.

he staple forming and inserting mechamsm is of the type of that disclosed in said United States Letters Patent to W. H. Borden, No. 1,016,930, February 13, 1912, except that the construction of the wire feeding mechanlsm has been modified and improved to provide room in which the shoe to be lasted can be more'freely manipulated. Like the machine of the Letters Patent to Borden, above referred to, the illustrated machine compmses a driver bar 16 lifted against the act on of a spring 20 by a lifting cam 11 actlng upon a block 14 upon said driver bar,

and a feed roll 90 operated by connectionsto a slotted lever 100, more fully described in said Letters Patent to Borden, said slotted lever 100 being in turn rocked by a second lever 106 having an arm (not shown) which carries a cam roll entering a cam groove in a cam disk on the main shaft 12 of the machine. v

The wire which forms the staples is fed to the staple forming mechanism n substantially the same manner as in the machine shown in said Letters Patent'to W. H. Borden, and is cut by cutting mechanism of substantially the same constructionj The severing mechanism comprises a stationary cutter 80 fastened to the carrier by "piece 86 on the actuator bar 87'; Said actuator bar is slidingly mounted ina guideway in the head and is provided with rollers 88 and 89 which cooperate with the cam 12 on the main shaft, said cam operating to move the actuator bar, and consequently the cutter bar, positively in both directions, the

connection formed by the L-shaped piece and the hook-shaped end on the cutter bar permitting said cutter bar to move laterall with the carrier 70 in which it is mounte This forms a very efficient method of actuat-' ing the movable cutter as theactuator bar and the cutter-carrier bar both move in the same direction, so that very little power is re uired for moving the cutter-carrier bar.

5 in the machine shown in said Letters I illustrated machine differs in its construction and arrangement from the corresponding lever of the machine shown in the Letters Patent to W. H. Borden above identified. In order that the shoe may be rocked freely about the lasting tool 144, particularly when operating in deep shanks of mens or womens shoes, the fulcrum for the lever 140 has been located at 146 at a point above the feed roll 90, and the presser roll 142 is therefore moved laterally with respect to the feed roll 90, instead of downwardly, to release the wire. A spring 147, located between the arm of the lever 140 which extends above the fulcrum 146 and a bracket arm 148 upon the machine head, operates to maintain the presser roll 142 yieldingly in pressing relation to the feed roll 90. During the cutting operation the action of the plunger 7 5 upon the stop 76 rocks said lever 140 about its fulcrum 146 and moves the presser r011 142 toward the left out of pressing relation to the feed roll 90. As clearly disclosed in the drawing, guides 145 and 149 are provided for causing the wire to travel in a curved path about 'the feed. roll 90.

As will be clear from a consideration of the staple forming and driving mechanism disclosed, the lasting tool 144 is also a nozzle for guiding the staple fastening while it is being driven into the shoe. It will be observed also that the feed rolls are in a plane above that of the upper end of the nozzle and therefore in a plane considerably above that of the lower end of the nozzle where the stapling operations on the work take place.

The wire 150, which is preferably comparatively fine, is wound upon a spool 152 which turns upon a stud 154 upon a bracket 156 carried by the machine head, any suitable means being provided for frictionally retarding the turning of said spool. To prevent too rapid unwinding of the spool and also to prevent the pull of the wire during the feeding operation from drawing the wire down into the lower coils of the spool, thus causing it to kink or tangle, a tension device is provided which comprises a grooved wheel 158 carried by a spring supported plunger 160 guided through the spring socket 162 and limited in its downward movement by a pin 164 traveling in a slot in said socket, whereby it prevents the plunger from turning in the socket.

Having thus described this invention, what is claimed as new and is desired to secure by Letters Patent of the United States is:

1. In a staple making and driving machine, means for feeding the staple wire, means for cutting the wire into staple lengths, said wire feeding means comprising feed rolls arranged in substantially horizontal alinement, a member for supporting one of said rolls and movable about a pivot located above said rolls to carry the supported r011 toward and from the other roll, and means for operating the member in eachcycle of operation of the machine to control the feed of the wire by the feed rolls.
